9 Page 2-2. INSTALLATION 2. General A basic system consists of a PGR-6200, a PGR-0CIM, and three -A- or -A-secondary linecurrent transformers. Earth-fault protection can be provided from a core-balance CT or from phase CT s. A core-balance CT (-A, -A, or PGC-3000 series) is recommended. In addition to a single PTC/RTD input provided on the PGR-6200, up to three PGA-020 modules (eight RTD inputs per module) and one PGA-040 differential module can be connected to a PGR The PGR-6200 switch-mode power supply is rated 6 to 26 Vac and 80 to 27 Vdc. All modules can be mounted in any orientation. 2. PGA-020 Temperature Input Module Outline and mounting details for the PGA-020 are shown in Fig The PGA-020 will fit inside most motor RTD-termination junction boxes and it is certified for use in Class I, Zone 2 hazardous locations. The PGA-020 can be surface or DIN-rail mounted. 2.6 PGA-040 Differential Current Module Outline and mounting details for the PGA-040 are shown in Fig 2.8. The PGA-040 can be surface or DIN-rail mounted. 2.2 PGR-6200 Motor Protection Relay Outline and details for PGR-6200 panel-mounting are shown in Fig. 2.. The PGR-6200 mounts in a 92 mm (3.62 ) ¼ DIN square cutout and is secured by a panel-mount clamp. Insert the PGR-6200 through the panel cutout and slip the panel-mount clamp over the PGR-6200 body. Slide the clamp forward until the latch tabs snap into the mating holes. Lock the unit in place by tightening the four clamp screws against the panel. Caution: Do not over tighten the clamp screws as this may deform the clamp and release the latch tabs. Outline and details for PGR-6200 surfacemounting are shown in Fig Ensure that the L/S switch is set before installing surface-mounting brackets. See Section for switch positions. A detailed installation instruction sheet is included with the PGK-0SMK, Surface-Mounting Hardware Kit. 2.3 PGA-0CIM Current Input Module The PGA-0CIM can be surface or DIN-rail mounted. Outline and mounting details are shown in Fig To minimize CT-lead burden, a PGA-0CIM can be located close to the CT s. The PGA-0CIM terminates phase- and earth-fault-ct secondaries shorting blocks are not required for PGA-0CIM outputs. 2.4 Sensitive Earth-Fault CT s Outline and mounting details for the PGC-3026, PGC-3082, and PGC-340 are shown in Figs. 2.4, 2., and 2.6.

20 Page Wiring Connections 3.2. PGR-6200 Connections The PGR-6200 wire-clamping terminal blocks accept 24 to 2 AWG (0.2 to 2. mm 2 ) conductors. These terminal blocks unplug to allow the PGR-6200 to be easily removed Supply Voltage Derive supply voltage from the line side of the motor controller or from an independent source. Connect supply voltage to terminals 2 and 3 (L and L2/N) as shown in Fig. 3.. In 20-Vac systems, L2/N is designated as the neutral conductor. For direct-current power supplies, use L for the positive terminal and L2/N as the negative terminal. Ground terminal 8 ( ) CIM Input Connect the PGR-6200 to the PGA-0CIM as shown in Figs. 3.6 and 3.7 using the cable provided Digital Input A 24-Vdc digital input is provided on terminals 2 and 26. This input is polarity sensitive. For a logical, terminal 26 must be positive with respect to terminal 2. See Section The current-limited 24-Vdc source (terminals 27 & 3) can be used to power the digital input Analog Output The analog output is switch selectable as self powered or loop powered. For the self-powered connection, set the L/S switch to the S position. The self-powered connection is shown in Fig. 3.2 (a). The analog output is referenced to the I/O module supply, terminal 27. For the loop-powered connection, set the L/S switch to the L position. The loop-powered connection is shown in Fig. 3.2 (b). In looppowered operation, the analog-output is isolated from all other PGR-6200 terminals. a) SELF POWERED (S POSITION) AA AB AA AB b) LOOP POWERED (L POSITION) LOOP - SUPPLY RECEIVER TERMINATION RECEIVER TERMINATION FIGURE 3.2 Analog-Output Connections PTC or RTD Input (Local) The temperature-sensor input on the PGR-6200 can be configured for either PTC or Pt00 RTD operation as shown in Fig a) PTC +t b) Pt00 RTD t 9 TC 8 TB 7 TA 9 TC 8 TB 7 TA FIGURE 3.3 Local Temperature-Sensor Connections I/O Module Interface The I/O module interface supplies power and communications to optional I/O modules such as the PGA-020 and PGA-040. I/O module communication is based on the twowire multi-drop TIA-48 standard but uses a proprietary protocol. Overall line length must not exceed.2 km (4,000 ). For line lengths exceeding 0 m (33 ), 0-Ω terminations are required at the cable ends. I/O modules are supplied with 4 m (3 ) of interconnection cable. See Fig Note: I/O communication is shared with the display. Incorrect wiring can cause the display and keypad to freeze.

21 Page RS/EIA/TIA-232 Communications An RJ-4 TIA-232 connector is provided on the rear panel of the PGR This port uses Modbus RTU protocol to communicate with PGW-COMM PC-interface software. For Modbus RTU protocol, see Appendix D. The slave ID and communication baud rate are set in the Setup Hardware Local Comms menu. Table 3. shows the pinout for the optional PGA-0420 adapter for operation with PGW-COMM. See Fig 3. for RJ-4 pinout. For a USB connection, use an PGA-0440 adapter. TABLE 3. PGA-0420 Adapter Pinout SYMBOLIC NAME RJ-4 DB9 RI/DSR 9 CD 2 DTR 3 4 SG 4 RD 2 TD 6 3 CTS 7 8 RTS PGA-0CIM Connections The PGA-0CIM CT-input terminal blocks accept 22 to 0 AWG (0.3 to 4.0 mm 2 ) conductors. The remaining PGA-0CIM clamping blocks accept 24 to 2 AWG (0.2 to 2. mm 2 ) conductors. The PGA-0CIM contains four signal-conditioning interface transformers which are interconnected as shown in Fig. 3.. These transformers isolate the PGR-6200 from the phase and earth-fault CT's. The PGA-0CIM eliminates the need for CT shorting contacts when the PGR-6200 is disconnected. Phase-CT and earth-fault-ct secondaries can be simultaneously grounded through terminal 22 and a jumper to terminal 20. For applications where the CT secondaries must be grounded at another location, the CT secondaries can be isolated by removing shorting screws A, B, and C through holes in the bottom of the PGA-0CIM. See Figs. 2.3 and 3.. Note: A-B-C phase sequence and polarity must be observed when connecting phase CT s. See Section Connect the PGA-0CIM to the PGR-6200 as shown in Figs. 3.6 and 3.7 using the cable provided. TB3 TB R S E X Y E F E F2 C OM C B A A B C R S R S R S TB NOTES:.

22 Page Standard Standard connections with earth-fault CTs are shown in Fig Dotted lines indicate -A-CT connections. Use shielded cable for PGC series current-transformer connections. Ensure only current-carrying phase conductors pass through the earth-fault-ct window and that ground conductors do not Residual Earth-Fault The wired residual earth-fault connection is shown in Fig. 3.7 (a). Dotted lines indicate -A-CT connections. Use three identical CT's for this connection. The PGR-6200 also calculates residual current. See Section Two-CT The two-ct connection is shown in Figs. 3.7 (b) and 3.7 (c). Dotted lines indicate -A-CT connections. Since this connection derives the current in the unmonitored phase, it should be used only in retrofit applications where it is not possible to install a third CT. a) STANDARD CONNECTION -A OR -A EARTH-FAULT CT PGR-6200 S H 29 2 E F 22 C O M 6 C B 4 A 3 A A R S E X Y E F PGA-0CIM 7 E F2 6 C O M C 4 B 3 A R S R S R S CT A CT B CT C b) STANDARD CONNECTION WITH PGC-3000-SERIES CURRENT TRANSFORMER PGC-3XXX PGR-6200 S H 29 E F 22 2 C O M 6 C B 4 A R S E X Y E F PGA-0CIM 7 E F2 6 C O M C 4 B 3 A R S R S R S A A A A A A BLUE BROWN GREEN RED WHITE BLACK A A A A A A BROWN BLUE GREEN RED WHITE BLACK S TERMINALS ARE GROUNDED THROUGH TERMINAL 22 S AND E TERMINALS ARE GROUNDED.

24 Page PGA-020 Connections and Address Selection Connect the PGA-020 Temperature Input Module to the PGR-6200 using the four-conductor shielded cable (Belden 324A or equivalent) supplied with the PGA-020 as shown in Fig The PGR Vdc supply can power up to three PGA-020 modules. Connect RTD s to the PGA-020 as shown in Fig 3.8. When the RTD module is installed in a motor junction box, RTD-lead shielding is not required. PGA-020 terminal blocks accept 24 to 2 AWG (0.2 to 2. mm 2 ) conductors. Connect surge-protection (SPG) terminal 20 to terminal 9 ( ) and ground terminal 9. The PGA-020 has two switches to select its network address. See Fig Up to three PGA-020 modules can be connected to the I/O MODULE bus, and each RTD-module address must be unique. If one module is used, address must be used. If two RTD Modules are used, addresses and 2 must be used. If three RTD Modules are used, addresses, 2, and 3 must be used. Table 3.2 shows the address selection format. TABLE 3.2 PGA-020 Address Selection ADDRESS SWITCH SWITCH 2 0 (Off line) Open Open (First RTD module) Closed Open 2 (Second RTD module) Open Closed 3 (Third RTD module) Closed Closed PGA-040 Connections Connect the PGA-040 Differential Input Module to the PGR-6200 using four-conductor shielded cable (Belden 324A or equivalent) as shown in Fig Connect the surge-protection (SPG) terminal to terminal 4 ( ), and ground terminal 4. The PGA-040 CT-input terminal blocks accept 22 to 0 AWG (0.3 to 4.0 mm 2 ) conductors. The remaining PGA-040 clamping blocks accept 24 to 2 AWG (0.2 to 2. mm 2 ) conductors PGR-6200 Summation The PGR-6200-summation connection uses three phase CT s and three differential CT s as shown in Fig Both CT-ratio and CT-saturation characteristics must be matched to avoid differential currents under motor starting and running conditions. The PGA-040 module should be located near the PGA-0CIM to minimize CT-wire length. It is preferred to use three dedicated phase CT s and three core-balance differential CT s as described in Section For the delta connection, the FLA Rating is set equal to the motor s full-load current multiplied by DIF Summation The DIF-summation connection uses six differential CT s as shown in Fig. 3.. Both CTratio and CT-saturation characteristics must be matched to avoid differential currents under motor starting and running conditions. It is preferred to use three core-balance CT s as described in Section This six-ct connection allows the CT s and PGA-040 to be placed near the motor to minimize power-cable and CT-lead length Cable Restraint All conductors should be restrained within 00 mm (4") of the terminal blocks. Four cablingrestraint points are provided on the PGR-6200 rear panel. Secure cables to the PGA-0CIM, PGA-020 and PGA-040 using the cable-tie eyelets and the cable ties provided. See Figs. 2., 2.3, 2.7 and Dielectric-Strength Testing Dielectric-strength testing can be performed only on CT inputs, supply-voltage input, and output relays. Unplug all other I/O and remove the PGA-0CIM connection (terminal 22) during dielectric-strength testing Core Balance The core-balance connection uses three differential CT s as shown in Fig To minimize power-cable and CT secondary lead lengths, both the differential CT s and the PGA-040 can be located near the motor. The primary rating of the differential CT does not have to match the phase- CT primary rating and is usually selected with a lower ratio resulting in more sensitive differential protection. The core-balance method avoids CTmatching issues and is the preferred connection.

See Appendix B Phase-CT Inputs Menu: Setup System Ratings CT Primary The CT-primary setting range is to,000 A. To maintain specified accuracy, phase CT s should be selected with a primary rating between 00 and 300% of motor full-load current. For A-B-C sequence, the +Seq I display value is larger than the Seq I 2 display value and positive current unbalance is indicated. Negative current unbalance will be indicated if the phase sequence is B-A-C. If negative unbalance is indicated, correct the phase-ct connections. Severe current unbalance may be indicated when phase-ct polarity is incorrect Earth-Fault-CT Input Menu: Setup System Ratings EF Source Menu: Setup System Ratings EF-CT Primary The EF Source menu selects the earth-fault source as Calculated (3I 0 ) or Measured (I ct ). The Calculated (3I 0 ) selection uses the 3I 0 value obtained from the sequence-component calculation and is based on the phase currents only. Set the EF-CT Primary to the phase-ct-primary rating when Calculated (3I 0 ) is selected. The Measured (I ct ) selection uses current measured by an earth-fault CT or the residual connection. Set EF-CT Primary to the earth-fault- CT-primary rating when an earth-fault CT is used. For the sensitive PGC-3082 and PGC-340 earthfault CT s, set EF-CT Primary to A. Set EF-CT Primary to the phase-ct-primary rating for the residual-ct connection. The setting range for the EF-CT-Primary rating is to,000 A. Note: Calculated 3I 0 does not detect CT saturation. Enable overcurrent protection when earth-fault current can exceed times the phase-ct primary rating. Note: 3I 0 and I ct values will be shown in the Metering Earth Leakage display regardless of the EF Source selection or CT connections. Note: For the residual connection and Calculated (3I 0 ) selection, the earth-fault-trip setting should be greater than % Motor Data Menu: Setup System Ratings Menu: Setup Protection Overload In the System Ratings menu, motor data must be entered for the FLA Rating (full-load current), Frequency, and Service Factor. Set Frequency at 0 Hz, 60 Hz, or Variable. Use Variable for adjustable-speed drive applications. LR Current (locked-rotor current), LR Time Cold (cold locked-rotor time), and LR Time Hot (hot locked-rotor time) must be entered in the Setup Protection Overload menu to provide customized overload protection. See Section.2.

29 Page Output Relay Assignment Menu: Setup Relay Outputs Relay x Menu: Setup Relay Outputs RY Pulse Time Each of the three output relays can be assigned to one of the functions listed in Table 4.2. More than one relay can be assigned the same function. Trip and alarm assignments operate in the selected fail-safe or non-fail-safe mode. The default assignment for Relay is Trip, for Relay 2 is Alarm, and for Relay 3 is None. The default mode setting for all three relays is Fail-Safe Digital Input Menu: Setup Digital Input Input Function Menu: Setup Digital Input Start Bypass Menu: Setup Digital Input Bypass Delay Menu: Setup Digital Input Trip Delay The digital input can be assigned to one of the functions listed in Table 4.3. When the digital input is assigned the Trip function, Start Bypass, Bypass Delay, and Trip Delay set points become active. When Start Bypass is enabled, the digital input is bypassed during a start for the duration specified by Bypass Delay. Start detection is based on motor current. After the Bypass Delay, the digital input is enabled and a trip occurs if the digital-input voltage is removed for the time specified by the Trip Delay. If Start Bypass is disabled, Bypass Delay is not used and the digital input Trip function is always enabled. The bypass feature can be used in pumpcontrol applications to allow time for a pressure switch to close. When the digital input is assigned to Reset, trips can be reset using an external reset switch. The Reset input is a one-shot reset and requires a transition from open to closed. Maintaining a reset switch closure does not inhibit trips. When assigned to Program Enable, password protection is disabled and program access is a function of the digital-input state as defined in Table 4.3. TABLE 4.3 Digital-Input Functions FUNCTION STATE () Trip = No Trip 0 = Trip (Delay selectable, reset required) Reset = Reset Trips Program = Program changes allowed Enable 0 = Program changes not allowed Reduced OC = Reduced Overcurrent set point not operational (ROC = Off) 0 = Reduced Overcurrent set point operational (ROC = On) None No assignment (Default) () = 24 Vdc applied, 0 = 24 Vdc not applied Password is disabled.
